•WARNING
Before removing the valve from service,
to avoid personal injury, you must:
• Depressurize the system
• Cycle the valve
• Purge the system to remove any residual
system media left in the valve
NOTICE
Do not scratch any sealing surfaces while
following these instructions. Scratches
on sealing surfaces may affect valve
performance.
3. Remove the gland nut using an open-end wrench.
4. Remove and discard the following components:
gasket (if applicable), cover/cone ring, poppet, and
spring.
5. Clean the valve body and gland nut. Ensure that the
threads are not damaged or galled.
#2 Disassembly
2. Lube the O-ring and the poppet assembly lightly
with Christo-Lube®MCG 111 lubricant applied to
the entire largest outer diameter (OD) surface of
the poppet. Assemble into the body on top of the
spring. For a ball seal, make sure the round ball part
is facing upward. For a soft seal, make sure that the
end with the O-ring faces away from the spring.
3. Ensure the poppet moves freely inside the body by
pushing down on the poppet with the dowel rod.
4. For assemblies with cone and thread or FK series
end connections, lube the external angles of the
cover by applying Moly-Lit™anti-seize lubricant
lightly.
For assemblies with NPT end connections, lube the
external angles of the cone ring by applying Moly-Lit
anti-seize lubricant lightly.
